BACKGROUND: Use of large clinical and administrative databases for orthopaedic research has increased exponentially. Each database represents unique patient populations and varies in their methodology of data acquisition, which makes it possible that similar research questions posed to different databases might result in answers that differ in important ways. QUESTIONS/PURPOSES: (1) What are the differences in reported demographics, comorbidities, and complications for patients undergoing primary TKA among four databases commonly used in orthopaedic research? (2) How does the difference in reported complication rates vary depending on whether only inpatient data or 30-day postoperative data are analyzed? METHODS: Patients who underwent primary TKA during 2010 to 2012 were identified within the National Surgical Quality Improvement Programs (NSQIP), the Nationwide Inpatient Sample (NIS), the Medicare Standard Analytic Files (MED), and the Humana Administrative Claims database (HAC)...

BACKGROUND: Chronic kidney disease (CKD) remains an independent predictor of cardiovascular morbidity and mortality. CKD complicates referral for percutaneous coronary intervention (PCI) in non-ST-segment-elevation myocardial infarction (NSTEMI) patients because of the risk for acute kidney injury and the need for dialysis, with American College of Cardiology/American Heart Association guidelines underscoring the limited data on these patients. METHODS AND RESULTS: Using the National Inpatient Sample to analyze hospitalizations in the United States from 2004 to 2014, we sought to assess PCI utilization and in-hospital outcomes in NSTEMI admissions with CKD...

INTRODUCTION: Timing of intervention and complication profiles in surgical repair of craniosynostosis have been widely debated. Early intervention is frequently promoted as a means of decreasing morbidity while maintaining favorable outcomes via minimally invasive techniques such as endoscopic strip craniectomy. Immediate postoperative morbidity due to complications of early vs late intervention remains a key element in comparing timing and technique for craniosynostosis repair. In addition, concurrent fronto-orbital advancement with open cranial vault remodeling may increase the risk of postoperative complications...

OBJECTIVE: Acute mesenteric ischemia (AMI) continues to be one of the most devastating diagnoses requiring emergent vascular intervention. There is a national trend toward increased use of endovascular procedures, with improved survival for the treatment of these patients. Our aim was to evaluate whether this trend has changed the treatment of AMI and the subsequent impact on length of hospitalization and hospitalization costs. METHODS: We identified all patients admitted for AMI from the National Inpatient Sample from 2004 to 2014 who received open surgical revascularization (OPEN) or an endovascular intervention (ENDO)...

BACKGROUND: Context: Degenerative changes in the cervical spine occur in an age-dependent manner. As the U.S. population continues to age, the incidence of age-dependent, multi-level, degenerative cervical pathologies is expected to increase. Similarly, the average age of patients with cervical spondylotic myelopathy (CSM) will likely trend upward. Posterior cervical fusion (PCF) is often the treatment modality of choice in the management of multi-level cervical spine disease. Although outcomes following anterior cervical fusion for degenerative disease have been studied among older patients (aged 80 years and older), it is unknown if these results extend to octogenarian patients undergoing PCF for the surgical management of CSM...
